Know what you are going to bring to the interview, your strengths weaknesses, how you are going to add value to the team, what your goals and purpose for applying to the position and why. Have scenerios of how you dealt with different situations that you may incurr ( difficult customer, difficult co worker, co workers not getting along affecting other co workers or clients etc.)

Awesome interview process, it was professional & courteous. The interview process is lengthy, but worth it in the end! I spend two years in this role and I loved it.
